The Fujifilm TCL-X100 II Tele Conversion Lens fits directly onto the FUJIFILM X100, X100S. This lens multiplies the focal range by a factor of 1.4x – converting 23mm to 35mm and 33mm to 50mm. The minimum working distance is then 14cm. The TCL-X100 is designed to keep chromatic aberration to a minimum while also using Fujinon’s Super EBC coating.
